3 Claims. (Cl. 235-433) This invention is for improvements relating tototalizer counting and displayin arrangements, and one of its objects isto provide improved transfer arrangements.

In order that the features of the invention may be made clear a briefdescription of the function of a totalizer will first be given.

The totalizer is primarily for use in public meeting places for countingthe number of sales of commodities, etc., or the number of investmentsmade by the people present. With one arrangement initiations of suchproceedings are made at ticket machines disposed at convenient placestermed boot and upon such a step being taken a ticket is endorsed withparticulars of the transaction such as the amount deposited and detailsspecifying the transaction entered into. As each negotiation is made thetotalizer displays to the public both the total amount deposited on eachinvestment, for example, and also the sum total or pool of all of thedeposits received.

It is convenient to consider the totalizer as comprising a number ofticket machines, totaliz- 7 ing apparatus for the amounts deposited oneach individual investment, the pool totalizing apparatus and theindicator or display.

Each ticket machine is provided with a set or a number of sets of keys.Each key is numbered and is allocated to a particular investment orbeing made in connection with a transaction which for the purpose ofthis specification will be designated by the No. 1 a key correspondingto that number in a set of keys arranged for 1 investments is operatedand causes a ticket to be endorsed and issued and the totalizingapparatus to register the amount of the investment and add it to thetotal for the particular transaction specified and to the sum total ofthe pool.

The display or indicating apparatus is located in a prominent positionand is controlled by the totalizing apparatus. There may be severaldisplays at different localities associated with the same totalizingapparatus.

When desired, for example at the end of th proceedings, arrangements areprovided to set the apparatus to zero in readiness for furtherproceedings.

According to the invention a transfer circuit arrangement for atotalizer comprises one relay adapted to operate fully prior to themovement of a registering switch into a zero position and to make anoutlet of a connecting switch associated with the next denomination anda second relay adapted to cause the release of the first relay after theconnecting switch has found the marked outlet.

According to one feature of the invention a transfer circuit arrangementfor a totalizer comprises one reiay adapted to operate fulLv prior tothe movement of a registering switch into a zero position and to mark anoutlet of a connecting switch associated with the next denomination anda second relay connected in series with the conductor marked by thefirst relay and adapted to cause the release of the first relay afterthe connecting switch has found the marked outlet.

According to another feature of the invention a transfer circuit for atotalizer comprises one relay adapted to operate fully. prior to themovement of a registering switch into a zero position and to mark anoutlet of a connecting switch associated with the next denomination anda second relay adapted to cause the release of the first relay after theconnecting switch has found the marked outlet and means whereby all thetotals received by the registering device of the higher denominationfrom that of the lower denomination are registered even when the deviceof the higher denomination is registering for another or a plurality ofother sources.

The invention will be more completely understood by referring to thefollowing description of one method of carrying it into effect whichshould be read in conjunction with the accompanying drawings. Thisdescription is, however, given by way of example only, and variousmodifications may be made by those skilled in the art without in any waydeparting from the spirit of the invention. It should be mentioned alsothat this arrangement is identical to that disclosed in thespecifications of U. S. patent application Nos. 482,878 and 482,880 ofSeptember 18th, 1930 which claim different features from those claimedherein.

Referring now to the accomp y drawings,

Figures 1 and 2 show a schematic layout of the totalizer.

Figures 3 to 10 inclusive, show circuit connections of various parts ofthe totalizer.

Figure 3 shows the circuit of three receiving switches RA, RB and RC forinvestments in the same transaction and the connections to investmentkeys at ticket machines for 2/-, 1 and 10 investments respectively:

Figure 4 shows the circuit of a registering switch UA for investments inan individual transaction. The same drawing is applicable for 2/-, 1 or10 investments:

Figure 5 shows the circuit of a relay group and relative display lamps.This drawing may be used for all denominations and also for amounts 50tional registering switches are shown at UD1 and switch UD for amountsof 100 or 1000, either invested in an individual transaction or for, thetotal pool:

Figure 7 shows the circuit of three receiving switches RTA, RTB, RTC forthe total pool investments of 2/-, 1 and 10 respectively, while Figure 8shows the circuit for a registering switch UT for the total poolinvestments of 2/-, 1 and 10:

Figure 9 is an inset portion at the top of Figure 4 and represents thecircuit of a transfer equipment associated with the registering switchfor 2-, 1 and 10 investments in individual transactions:

Figure 10 is an inset portion at the bottom of Figure 4 and shows theresetting key and associated relay.

Figure 11 shows the arrangement of lamps of a digit display and Figure12 shows an example of a. numeral being exhibited on a digit display.

Figure 13 is a table which relates to Figure 11.

Figure 14 is a drawing showing the way Figures 3 to 10 inclusive shouldbe arranged in order to facilitate tracing the various circuits to bedescribed. I

The schematic layout illustrated in Figures 1 and 2 will now bedescribed. The figures should be arranged so that Figure 2 is on theright-hand side of Figure 1.

Six ticket machines are shown in Figure 1; TMl, TM2 and TM3 representticket machines for 2s. 0d. investments, TM4 and TM5 represent machinesfor 1 investments and TM6 a machine for 10 investments.

Three receiving switches are shown for receiving investment ortransaction No. 1 at RAl, RBI and RC1. Outlets of receiving switch RAlare connected to keys KA-1 of ticket machines for 2s. 0d. investments.Outlets of switch R31 are connected to keys KBl of ticket machines for 1investments and outlets of switch RC1 are connected to keys on ticketmachines for 10 investments such as the one shown at KCl.

Registering switches for counting the number of investments received areshown at UAl, UB1 and U01, and are associated with receiving switchesRAl, RBI and RC1 respectively. Addiand T31, and at T01 and TDl transfercircuits are represented which are connected from one registering switchto another registering switch direct.

These transfer circuits operate so that when ten investments of onedenomination have been made one registration is effected on theregistering device for the next higher denomination, leaving theapparatus associated with the lower denomination free to receive tenfurther investments for registration. A decimal system of investments isemployed. Thus ten 2/ investments being equivalent to a single 1investment cause. through the medium of a transfer circuit, a singleregistration on the apparatus adapted to receive and register 1investments, and the apparatus for 2/- investments is left free toreceive further investments. Separate transfer circuits, similar to oneanother, are used for each device for individual investments and alsofor the pool registering apparatus.

The apparatus for other transactions is similar to that required for No.1, receiving switches RA2, BB2 and RC2 being connected to keys KA2, KB2and KCZ respectively of the ticket machines for 2s. 0d.. 1 and 10investments respectively. and receiving switches RA3, BB3 and RC3(Figure 2) being similarly connected to keys KA3, K83 and K03.

Switches RTA, RTB and RTC are shown in Figure 1 for receiving the totalpool of all investments made. Outlets from receiving switch RTA lead toticket machines for 2s. 0d. investments. They do not terminate on keysbut on a relay contact, not shown, which operates prior to the issue ofa ticket by the ticket machine. Similarly, outlets from receivingswitches RTB and RTC lead to ticket machines for 1 and 10 investmentsrespectively.

Registering switches are shown at UTA, U'I'B and UTC which areassociated with receiving switches RTA, RTB and RTC respectively, andadditional registering switches at UTD and UTE for counting 100 and 1000amounts.

Associated with each registering switch are remy groups GTA, G'IB, GTC,etc., and digit'display apparatus DTA, D'I'B, DTC, etc. Transfercircuits are represented at TTA, TTB, TTC and TTD.

It will be understood that a greater number of ticket machines andapparatus for more than three transactions and five denominations 0iinvestments may be provided. Also there may be a number of differentdisplays for each transaction and for the total pool. These would becontrolled by relay groups and registering switches the latter being, inturn, controlled by apparatus associated with the registering switchesrepresented in Figures 1 and 2.

The detail of the circuit operations will now be described. In thecircuit drawings relays and switches are referred to by capital letterswhich are placed on the drawings near their relative operating coils.Contacts are shown detached from their operating coils and aredesignated by small letters. The number of movable contacts possessed byeach relay or switch is indicated under its designation, thus (Figure7), denotes that relay YA has two movable contacts that are designatedgal and 11112;

(Figure 7) .denotes that switch RTA has five movable contacts, one, aninterrupter contact, is designated rtal, and others, which are wipers,are designated rta2, rta3, mm and 11:15. The source of electric supplyis shown as a battery for the negative pole and as an earth for theother potential. The supply need not necessarily be a battery; it may,for example, be supplied from a generator.

In the following description it will be assumed by way of example, thatan investment is made in a transaction specified by No. 1, but nodifferent principle is involved if an investment is made on any othernumber. Further it will be assumed at first that all switches and relaysare in the normal positions indicated by the drawings, and that1,988,626 then a 2s. 0d. investment is made. The various circuitdrawings should be arranged in the relative positions indicated bycontinuous lines in Figure 14 in which position it will be found thatthe switch designations tally with those on Figure 1. The dottedpositions indicate alternative positions of certain figures when theyare used in the description for difi'erent denominations.

The operator at a 2s. 0d. ticket machine operates a key, such as KA(Figure 3), thereby closing a circuit from earth, contact coal, relayCWA and resistance R1 in parallel, key KA, upper winding of relay LA tonegative battery. The key remains mechanically locked in its operatedposition. Relay CWA does not receive sufficient current to operate inthe above traced circuit; relay LA, however, does operate. Otherwindings of relay LA and windings of other similar relays are associatedwith diflerent ticket machines and with difierent outlets of thereceiving switch.

The operation of relay LA closes at its contact Zal a circuit fromnegative battery, magnet 01 receiving switch RA, contacts m1, Zal,conductor 23, terminal 24 (Figure 4) to earth at contact cal. Thereceiving switch is of a well-known type used in automatic andsemi-automatic telephony and having 25 outlets on each contact are orlevel. The receiving switches are connected in such a manner that theirwipers have no home or normal position and it will be assumed that theswitch is in the position shown before key KA is operated.

These receiving switches are of well-known type and have been fullydescribed in U. S. patent specification No. 1,693,027.

The magnet of switch RA will operate in the previously traced circuit,and open its interrupting contact ml; the magnet then releases and indoing so moves the wipers forward to the next -bank contact. The releaseof contact ral again closes the magnet circuit.

This action is repeated and the wipers move round until an outlet isfound which is connected to the operated key. All the outlets of switchRA are connected in a similar manner to the one shown, but theyterminate on keys of different 2s. 0d. ticket machines. When wiper m2reaches the outlet leading to the operated key, a circuit is closed fromearth, contact coal, relay CWA in parallel with resistance R1, key KA,wiper m2, conductor 25, terminal 26 (Figure 4) relay CA to negativebattery. Relay CWA still remains unoperated but relay CA operates andcontact cal opens a point in the previously traced circuit of the magnetof switch RA thereby arresting its motion.

Contact cal also closes an obvious circuit for auxiliary relay CXA.Relay CXA operates and the magnet of registering switch UA energizes inan obvious circuit closed by contact cwal. This switch is in generalsimilar in construction to receiving switch RA of the type described inU. S. patent specification No. 1,693,027 but it has fifty differentpositions. The various levels of 25 contacts are associated in pairs;thus wipers 11116 and um? are associated with one pair of levels thewipers being arranged at 180 to each other. The circuit arrangements aresuch that the switch has five normal or zero positions, that is, everytenth position is a normal position.

Contacts 0x02 and cxa3 close circuits for other registering switches,not shown, which control other displays when these are required. If thedisplays are some distance away it is preferable to provide a relay ateach of the distant ends for controlling the circuit of the relativeregistering switches; contacts 0:412 and c103 are then arranged to closethe circuit of these relays instead of directly closing the circuit ofthe registering switches.

Contact era-1 closes a circuit for relay SA from earth, contact 0x114,wiper ua4, terminal 27 conductor 28, terminal 29, relay SA to negativebattery. Relay SA operates and at contact sa6 is held operated fromnegative battery, relay SA, contact sa6, terminal 30, conductor 31,terminal 32 (Figure 10), contact of homing key KH to earth. The homingkey is common to a plurality of circuits and is left in the positionshown when inventments are being accepted by the totalizer.

The operation of the magnet of switch UA at contact ualO shunts relay CAby a resistance, R2. This resistance is not low enough to cause therelease of relay CA but the combined resistance 01' R2, relay CA and thewinding of relay LA in parallel is low enough to allow suflicientcurrent through relay CWA (Figure 3) at the ticket machine so that itwill now operate. Contact cwal closes an obvious circuit for relay COAand ticket machine motor JA. Relay COA operates and at contact coalholds the circuit of the ticket machine motor closed so that it isindependent of contact cwal. Contact coal also opens the circuit ofrelays CWA, LA and CA which release.

The relapse of contact cal (Figure 4) allows the receiving switch to bestepped to find another outlet should there be another investmentawaiting acceptance; it also opens the circuit of relay CXA. Relay CXA.releases. and at contact czral opens the circuit of the magnet ofregistering switch UA. The latter then releases and moves its wipersforward one step in the direction of the arrows.

Relay COA (Figure 3) is locked in operation by way of its own contactand the ticket machine motor causes a ticket to be printed and issued.When the motor has nearly completed its operation it causes the operatedkey to be released and also causes cam CM to push back contact coal intoits normal position. The circuits of relay COA and motor JA are therebyopened and the motor stops, also relay COA releases. These operations atthe ticket machine do not form any part of the present invention but aregiven merely for explanatory reasons.

The relapse of contacts c:ca2 and cxa3 (Figure 4) causes the registeringswitch magnets controlling other displays to release and advance theirwipers one step. The operation of the registering switches and digitdisplay controlling relays for these displays is similar to theoperation now being described so that the present description will serveboth purposes. As it has been assumed that the investment being made isthe first one on the particular transaction the registering switch UAwill have moved from its normal or zero position into position No. 1. Inthis position a circuit is closed for relay A (Figure 5) from earth,contacts sal and sa2 in parallel, wiper 14416 in position No. 1,conductor 33, relay A to negative battery.

Relay A will be the only one of the digit display control relays A, B,C, D and E associated with conductors 33 to 37 inclusive, to be operatedwhen switch UA is in its first oiT-normal position. This will result inlamps 2, 3, 6, 10, l4, l7 and 21 glowing in circuitswhich are completedby way of conductor 38, contacts sad and sa5 (Figure 4) in parallel toearth. Thus the circuit of lamps 2 and 3 is from negative battery by wayof each of these lamps in parallel and contact c2 to the earth onconductor 38; the circuit of lamps 6 and 14 is by way of contacts e2,a3, d1 and c3 to the earth on conductor 38; that of lamp 10 is by way ofcontacts c4 and e7; that of lamp 1'7 by way of contacts e6, d3, b8 anda7, and that of lamp 21 by way of contacts 06 and d7.

The various display lamps are arranged in a known manner such as shownin Figure 11, the numbered squares in Figure 11 correspond to theposition of those lamps in Figure 5 bearing the same numbers. In Figure12 the lamps that glow when the registering switch is in position No. 1are shown shaded, their relative location being such as to represent theoutline of numeral 1.

If other 2s. 0d. investment on the same transaction are made similarcycles of operations to the one described are completed; these result inthe registering switch advancing its wipers one step for every 2s. 0d.invested in the particular transaction with which it is associated.According to the position of the registering switch, circuits fordifferent combinations of relays A, B, C, D and E are completed, whichresult in different combinations of lamps being lit and thesecombinations form recognizable outlines of numerals 0, 1, 2 to 9inclusive. It is not thought necessary to trace out the circuits indetail in the case of each numeral. In Figure 13, however, a table isshown which gives the combinations of relays that are operated fordifferent positions of the registering switches and the numbers of thelamps that are lighted corresponding to each combination. The resultingoutline can then easily be discovered by referring to the position ofthe corresponding lamp numbers in Figure 11. The various combinationsare repeated for every 10 steps of the registering switch so that forone complete revolution of the switch the equivalent of 50 positions ispassed by the wipers and the connections to the combination relays arethus repeated five times. Iii-point switches could of course be used forthe registering switches but the arrangement illustrated allows 25-pointswitches to be used, that have now become a well recognized standard inautomatic telephone practice.

If a 1 investment be made the operation of the associated apparatus willbe similar to that already described for a 2s. 0d. investment. If a 1investment is received before a 2s. 0d. investment on any particulartransaction it is necessary to ensure that the 2s. 0d. display revealsthe numeral outline corresponding to 0. For this reason a contact, sa3,is provided which is connected to terminal 10 and from thence byconductor 39 to terminal 29 of the apparatus associated with theregistering switch for 2s. 0d. investment. When the SA relay associatedwith the registering switch for 1 investment is operated, its contact,sa3, closes a circuit for the SA relay associated with the registeringswitch for 2s. 0d. investment. As the latter switch is in a normalposition a circuit will be closed for relays A and E. According to thetable in Figure 13 lamps will glow revealing the outline of numeral 0.

When nine 2s. 0d. investments have been received the associatedregistering switch will have made nine steps from one of its homepositions, consequently when relays CXA (Figure 4) operates, as a resultof a tenth investment, contact cra4 will close a circuit from earth,contact 02114, wiper M4 or 14:15, terminal 45, conductor 44, terminal 43and relay T of the transfer equipment (Figure 9), to negative battery.

, Relay T operates prior to the movement of switch UA into a zeroposition and is held operated by way of its contact t1. Contact t2closes a circuit for relay TR by way of conductor 41 and a winding ofrelay LB, (Figure 3), associated with the receiving switch for 1investments. Relay LB operates and at its contact Zbl causes receivingswitch RB to find an outlet that has been made common to conductor 41the. subsequent operations being similar to those described in the caseof switch RA. Relay TR does not receive sufiicient current to operateuntil the associated registering switch for 1 investments has beenenergised to close contact ualO (Figure 4). It then operates, theconditions being analogous-- to those described for relay CWA in theticket machine for 2s. 0d. investments, and the registering switch for 1investments advances one step and causes the associated display to beadvanced accordingly. The effect on the digit display for 1 investmentsis, therefore, the same as if a 1 mvestment were made at the ticketmachine. The operation of relay TR opens the locking circuit of relay Tat contact trl; this causes the latter relay to release as its originaloperating circuit was broken when the registering switch for 2s. 0d.investments made its tenth step. As it is necessary to effect a transferfor each 10 steps of the registering switch terminal 45 (Figure 4) ismade common to other outlets of the switch accordingly.

On referring to Figure 3 it will be seen that the transfer circuit iscommoned to a number of outlets of the 1 receiving switch. This is donein order to ensure that a transfer is received by the 1 receiving switchbefore the 2s. 0d. registering switch has time to reach the nexttransfer outlet. The receiving switch may have to stop at other outletsbefore reaching one that is commoned to the transfer circuit.

In the drawings it will be seen that every fifth contact is connected tothe transfer circuit. This allows investments to be received at amaximum rate by the switch of the lower denomination and yet it ensuresthat a transfer will be registered by the switch associated with thenext denomination before the switch associated with the lowerdenomination can accept another ten investments for the next transfer.If the transfer were made direct to the registering apparatus therewould be the danger that, if a transfer and an investment were requiredat the same time, they would not both be added to the relative displaydigit. The arrangements described ensure that each transfer ispositively accepted without undue delay even if transfers are initiatedsimultaneously with investments from ticket machines. Further,simultaneous investments may be initiated on the same transaction fromdifferent ticket machines. Again, if a transfer or an investment isinitiated at the moment a wiper of the receiving switch is passing overthe associated contact, relay CA will either stop the switch at thatcontact and cause the investment to be registered and the ticket machineto operate, or, if it does not have time to do this, the receivingswitch will step past the contact without affecting either thetotalizing apparatus or the ticket machine. When, however, the receivingswitch wiper again reaches that contact, or one commoned thereto as inthe case of a transfer, relay CA will have a full opportunity ofoperating and will cause the investment to be registered.

The operation of the receiving switch and registering switch for 10investments is similar to that described for lower denominations. If a10 investment is received before a 1 or 2s. 0d. investment on the sametransaction the SA relay associated with the registering switch for 10investments closes a circuit for the SA relay for 1 investments which inturn closes a circuit for the SA relay for 2s. 0d. investments aspreviously described. This ensures that ciphers will be shown in boththe 1 and 2s. 0d. digit displays. As for the purpose of this descriptionit has been assumed that there are no ticket machines for a higherdenomination than 10 investments, the transfer from the 10 regsteringswitch may be made directly to the registering switch for 100 amountssince there is no possibility of investment signals arriving from aticket machine at the same time as a 100 transfer. Terminal 45 (Figure4) of the apparatus associated with registering switches for 10investments is therefore shown connected by dotted conductor 46, insteadof by conductor 44, to terminal 47 (Figure 6).

When the first transfer is made to the 100 registering switch a circuitis closed from earth, contact cxa4 (Figure 4), wiper M4 or MS, terminal45, dotted conductor 46, terminal 4'1 (Figure 6), and from thence in onebranch by way of contact sd6 and relay SD to negative battery, and inanother branch by way of dotted conductor 48, terminal 49, relay CD tonegative bat tery. Relay CD operates and contact cdl closes the circuitfor registering switch UD. Contacts cd2 and cd3 close circuits forregistering switches for other displays. These switches operate, andupon the release of relay CD which follows the release of relay CXA inFigure 4, they make one step forward. Relay SD controls circuits for theindicator relays and lamps which are identical to those alreadydescribed in relation to Figures 4 and 5. Terminal 53, however, which isconnected to contact M3 and which corresponds to terminal 40 in Figure4, is left disconnected as relay SD (Figure 6) will never be operatedbefore relay SA. The locking circuit for relay SD is by way of contactsd6, terminal 51, conductor 50, terminal 32 (Figure 10), to the earth atkey KH. Transfer circuit terminal 54 is connected by conductor 55 toterminal 4'? of the apparatus associated with the registering switch for1000 denominations. The operation of the latter is identical to that ofa 100 switch but terminal 54, relative to that denomination is leftdisconnected as it has been assumed for the purpose of this descriptionthat there are no other switches of a higher denomination.

The detailed description of the circuit oi. the pool totalizingapparatus will now follow; this circuit comes into operation when theCWA relay at a ticket machine operates.

It will first be assumed that a 2s. 0d. investment has been made, andthat relay CWA has operated as previously described. Contact cwa2 at the2s. 0d. ticket machine in Figure 3 then closes a circuit from earth,contact cwa2, conductor 56, relay YA (Figure 7), conductor 57, terminal71 (Figure 8), relay P to negative battery. Relay 'P is made common toother relays similar to relay YA that are associated with outlets of thesame totals receiving switch RTA which lead to different ticketmachines, a separate P relay being preferably provided for, say, everyten YA relays. Switch RTA is substantially identical with receivingswitches RA, RB and registering switches UA, U3 and a descriptionthereof is to be found in U. S. patent specification No. 1,693,027.Relays YA and P operate, the former at contact 11112 closes a holdingcircuit for both relays and disconnects conductor 56. Contact yal marksan outlet of switch RTA.

Contacts p1 and :22 (Figure 8) close a circuit from earth, contacts pland p2 in parallel, conductor 58, interrupting contact rtal (Figure 7),magnet of switch RTA to negative battery. The magnet operates, opens itsown circuit at contact rtal, then releases and causes the wipers to bemoved forward into the next position. This action is continued untilwiper rta4 reaches the contact marked by contact yal.

Contact p3 closes a circuit from earth, contact p3, terminal 59,conductor 60, terminal 61, contact st6, relay ST to negative battery.Relay ST operates and is held operated by way of contact st6, terminal62, conductor 63 to earth at key KH (Figure 10).

Relay ST (Figure 8) is identical with relay SA in Figure 4 and itsoperation results in the operation of an assembly of digit displayrelays and lamps identical with that shown in Figure 5, in the same wayas describedin connection with relay SA. This separate display assemblyindicates the pool total in the same way as the assembly associated withrelay SA indicates the total relating to an individual transaction.

As soon as the receiving switch wiper encounters the earth applied bycontact val this earth is extended by way of conductor 64, terminal 65(Figure 8), relay CT to negative battery. Relay CT operates and atcontact ct5 closes a circuit from earth, contact ct5, terminal 66,conductor 67, wiper rta2, relay XA to negative battery. Relay XAoperates and at contact .ral opens the circuit of relay YA and theoriginal operating circuit of relay P. Relay YA releases and relay Palso releases if there is no other circuit completed by way of anotherrelay similar to YA due to another investment awaiting acceptance. Inthe latter case the switch will continue to search for another markedoutlet. 11' no other investments are awaiting acceptance contacts p1 and102 open the driving circuit of switch RTA to prevent further movementof the switch. This prevents unnecessary wear of the switch. During thecycle of operations just described the switch will not have time to makemore than one additional step. It will be noticed that relay XA (Figure'7) is connected to two successive contacts of the receiving switch.This'ensures that relay XA operates even if the additional step referredto is made by the switch. Contact gal opening removes the marking on theoutlet of the receiving switch and the circuit of relay CT is thereforebroken, whether the wiper remains on this contact or whether the switchsteps to the next contact which, as Figure '1 indicates, has no wireconnected thereto.

Relay CT- therefore releases and its contact 1 oil causes a momentarypulse to be given to register switch UT which thereby moves its wiperson to the next contact. This results in the digit display relays andlamps being operated-in a manner similar to that already described inrelation to Figures 4 and 5. Contacts 0152 and ct3 close circuits forthe apparatus for the distant displays. Contact ct4 controls thetransfer circuit by way of wipers ut4 or ut5, terminal 68,

conductor 69, contacts yb2 and :cbl (Figure '7),

in the position for 1 investments) to the P relay of the registeringswitch associated with 1 pool totals to negative battery.

11, when relay XA operates, the earth on conductor 56 has not beenremoved at contact cwa2 (Figure 3), relay XA will be held operated bythis earth by way of contacts rail, in its normal position, and (cal inits operated position. This arrangement prevents the possibility of asingle momentary impulse causing a .double registration at the pooltotalizing apparatus as no circuit can be closed for relays YA and Puntil relay XA releases. The release of relay XA takes place either whenthe earth on conductor 56 is removed, or, if the momentary earth haspreviously been removed, after the release of relay YA.

Relays X13 and YB, associated with the receiving switch for 1 pooltotals are identical to relays XA and YA respectively associated withoutlets to 2s. 0d. ticket machines. A transfer from the total poolregistering switch for 2s. 0d. investments therefore causes the totalsreceiving and registering switches to operate in a similar manner tothat described in the case of 2s. 0d. investments.

Other-outlets of the receiving switches for 1 totals are connected toother relays, similar to X13 and YB, associated with 020122 contacts(Figure 3) at different 1 ticket machines the connections and circuitoperations being identical to the circuit shown and described for the2s. 0d. ticket machines. a

The operation of the registering switch for 1 pool totals is alsoidentical to the operation of the registering switch for 2s. 0d. pooltotals. If a. 1 investment be received before 2. 2s. 0d. investment, theoperation of relay ST (Figure 8) completes a circuit at contact st3 byway of terminal 72 and conductor '73 for the ST relay associated withthe registering switch for 2s. 0d. pool totals. The 2s. 0d. total pooldisplay iswthereby operated.

Transfers from the 1 pool totals registering switch are made to the 10pool totals receiving switch in the same manner as described for thetransfer of 2s. 0d. totals and the 10 receiving switches and therelative registering switches operate in a similar manner to thoseemployed for 1 investments. Terminal 68 of the transfer circuit from the10 pool totals registering switch is, however, connected by way ofdotted conductor '74 to terminal 47 (Figure 6) of the registering switchfor 100 amounts.

The equipment and the circuit operation for registering 100 and 1000amounts for totals is identical to that described in the case of 100 and1000 amounts for individual horses and it is not thought necessary torepeat this description.

At the conclusion of the proceedings the totalizer must be returned tonormal in readiness for further or future operations. For this purposekey KH (Figure 10), is thrown thereby disconnecting all SA, SD and STrelays and completing an obvious circuit for relay H. The various SA, SDand ST relays release causing the display lamps to be extinguished andrelay H operates and closes circuits for all registering switchescontrolling primary displays that are off their normal positions. In thecase of a 2s. 0d. registering switch, for example, a circuit is closedfrom earth, contact hl, terminal 75, wiper mm or ua3, contact ual,magnet of switch UA to negative battery.

'relay YB, conductor 70, terminal '71 (Figure 8 The magnet operates andopens its interrupting contact ual thereby causing the wipers to bemoved forward to the next position. This action is repeated until theswitch returns to-anormal position where there is no connection to themagnet; further stepping is thus prevented.

Relay H has other similar contacts not shown which are connected tocorresponding terminals on other registering switches. These terminalsare designated 76 and 77 on Figures 6 and 8 re- 3 spectively. When thereare a large number of transactions involved it is preferable to provideseveral relays similar to relay H. These may be all controlled by key KHwhich may be provided with additional contacts if necessary. Theregistering switches controlling distant displays are returned to normalin a similar manner by a relay identical to relay H which is operated byadditional contacts on key KH not shown.

When it is desired to make different classes of investments thearrangements described are duplicated for each class except key KH andrelay H which may, if desired, be made common to the apparatus providedfor each class.

While in the foregoing description the apparatus is referred to asemployed for the purpose of totalizing the number of sales or the numberof investments made or similar transactions, it must be understood thatit may also be used for many other less serious purposes and is notlimited solely to those applications above referred to. For example, itmay be used for amusement purposes, at all kinds of race and likemeetings where it is desired to register investments made by the publicupon various events in the programme, and such use must be understood tofall within the scope of the invention herein described.

I claim:

1. A transfer circuit arrangement for a totalizer comprising one relayadapted to operate fully prior to the movement of a registering switchinto a zero position and to mark an outlet of a collecting switchassociated with the next denomination, and a second relay adapted to.cause the release of the first relay after the collecting switch hasfound the marked outlet.

2. A transfer circuit arrangement for a totalizer comprising one relayadapted to operate fully prior to the movement of a registering switchinto a zero position and to mark an outlet of a collecting switchassociated with the next denomination, and a second relay connected inseries with the conductor marked by the first relay and adapted to causethe release of the first relay after the collecting switch has found themarked outlet.

3. A transfer circuit arrangement for a totalizer comprising one relayadapted to operate fully prior to the movement of a registering switchinto a zero position and to mark an outlet of a collecting switchassociated with the next denomina tion, a second relay adapted to causethe release of the first relay after the collecting switch has found themarked outlet, and means whereby all the totals received by theregistering device of the higher denomination from that of the lowerdenomination are registered even when the device of the higherdenomination is registering for another or a plurality of other sources.
